In Ehis ring Ehe box F, containing Ehe reprodueing mechanism, is adjusEably held. The arm C also supports adjustable arme E, which are adapEed Eo SupporE Ehe horns N. is flanged Eo fit EighEly 0n Ehe periphery 0f Ehe box F and is reeessed aE J and K Eo admiE Ehe projecting mechanisnn 0f Ehe reproducer.
